PLOW.,

To all whom t may concern: l y

Be it known'that I, LLOYD W. STIGKLEY, a citizen of the United States,anda resident of South Bend, in the county of Saint Joseph and Stateof'Indiana, have invented certain new and useful Improvements in Flows;

and l vdo hereby declare the following to be a full, clear, and exactdescription of the invention, such aswill enable others skilled 1 in theart to which itl appertains to' make and use thel same.

This invention relates to improvementsin plows. and more particularly`.to such as are intended to be tractordrawn,-the inven# tionbeingembodied, in the present instance, in a plow structure 'especially welladapted Y foruse in plowing in orchards, said structure being low-down,withf no upwardly projecting levers which mightcon'iict with limbs oftrees', and with thailand-'wheel located insideof the line oftravel ofthe plow bases and with' 'the hubs of said wheels inside of theplane'ofthe outer edges ofthe rim portions of the wheels.y l y Y l. zUThe object of my present invention is to provide a plow lwithwheel-operated rliftV mechanism which' shalljbe simple in con.V

struction 'and which shallembod tripping mechanism for controlling/thelifting and I lowering of the plow, which shall comprise but few parts;be accurate in operation;

which willnot be liable te get out of order and which shall be easy andsimple to ma! lside elevation; Fig. "3 is anfenlarged plan` View showingthe controlling means of the power `lift mechanism, and adjustingdevices; Fig. 4: is a section on vthe line ffl- 4 of Fig. v3 withcertain parts omitted-,Fig 5 isa partial plan view showing" thepositions-Of the trip andllocking-up devices'when lthe plow hasbeen'raised; Fig. 6 'is an elevation,

vvided with lugs 22 vkeyed to theland-whee'l- .axle 1,11 and clampedthereto `"by meansof Vbolts 23. l

The lifting mechanism Vhereinafter described cooperates with thelandwheel and its crank axle and as thel furrow-wheel axle is j -mountedindependently of the land-wheel axle, it isxnecessary that af connectionvshall be effectedbetween these axles' which will cause movement of bothaxles during the op,-V eration of` raising the vplow ,iframe In thepresent instance, the'bearing sleeve 18 whichv is clamped and keyed tothe crank aikle`14is provided with an" arm @1 8L and this yarm engages amember' 18b adjustablyrsecured to an i Varmlc rigidlyattachedto thefurrow wheel crank axle. 19; K

The rear end of the structure is supported by VVa Vfollower wheelV24,;the standardl axle 25Y of which is mounted a bearing bracket26'a11d the latter is "pivoted to ajbracket 27 scoured to therearendSpOIfCiOn,ofthe-rear v v'plowbeam or thestandard'portion 9a thereof.`Ailever 28, pivote-d 'betweenits ends to the bracket 27, cooperates withthel pivoted bearingf bracket 26 tof. raise lthe rear. end of' theplowlstructure' on Athe. follower wheel 24, Aand inl order' that therear end of the kicking-off cam 50 and a spring 51, lo-

'.{Thev brackets 10` and 1-1 are provided at their forward ends withbearings32f33 .for a shaft 34 disposed transversely Cover the lbeams2-2fof the plow frame and projeeting [outwardly beyond each of saidbeams the lpr'ojectingend of thegshaft 314 nearest theland-side of theplow, a segmental -rack'35, is secured andthe hub 16 of the land wheel17has secured thereto, a gear 4or .cage-wheel 36 withv wliichsaidsegmentalraeq will be caused to mesh to effect therfaisingfof the plowframe.

The vrear end ofthe arm40 (with which the spring 37 is connected) is bifurcated andstraddlesthe axle 14 andthe for:l ward end of this arm is provided with2L ring or collar 41 mounted on one end of thev sleeve 39 and withinwhich said sleeve Y Ina-y turn freely. In order to limit the movementvofthe sleevef 39 and shaft 3,4

when the latter turns in la directionV toY raise the toothedsegment,'said Vsleeve is provided i with a stop lug 42 to engage a stoplug 43 on the ring orcollar 41. 1n this f way the upward movement of thevsegment will ,be limited.

`Whe`nthe plow frame shall' beeirfv raised as 'above described, it willbegheld in elevated position'by therope'rajtion of aflofcking-up .device-61. Y This device comprises links 6 2ifsecuredv togethery at one Vendand pivotedat their other endstor lugsi63 on the bracket 11, and Va linkV64`having a movable connection at one end with the- 4links 62,

y(between the ends of the latter) and pivoted atits other endto the arm31, -whichf latter is, as before stated, secured tothe crank ,axle

isoVV thus turned, its camA lugs ivillfcop'erate i with ,the cam lugsonl the cam ring 41` and result .in causing 'the cain'ring 47 andthe. 'Ysleeve 48v on which jitis mounted, to 'inove 14. V'Vhen the plowframeshall have been raised, the locking-up device will drop and overlie thekickingpif vcam 50 of the sleeve 48 andthe `link 64 of said locking-*updevice will drop between the lugs 63 on bracket 11,`so that the pivotalconnection the plow frame descends, the crank axle 14 will becaused toturn and motion ,willbe transmitted, through the arms 54, 56 and link 55to the cam ring 47, to turn the latter and movey its lugs out of linewith the lugs of the cam ring 41, when themembers of the trip deviceswill be moved' to coperative relation bythe actionk of thespring 51..

It will be observed that the lifting devices above described effect theraising `of the forward portion of the plow frame,b`ut during theraising operation, the'turning ofthe crank axle 14 will cause motion tobe transinitted, through the medium of the arm 31, rod 30 and link 29,to the lever 28"and the coperation of the latter with the pivotedbearing bracket 26, will cause such movement of the standard axle 25 asto effect the raising of the rear end ofthe plow,frame en the followerwheel 24. When the for- '\vai'd portion of the j )lowframe is droppedaspreviously explained, the arm 31 on the crank axle 14 willmove inthereverse direction, and the dropping of the rear part of the framewill be permitted, as will be readily understood. -f

The plow structure may be provided with a balancing or lifting spring65, oneendof which is attached to an armf66secured to' 'l the crank axle14 and the otherlendis adjustably connecte'd,fthrough the,mediumv ofy athreaded rod 67 with'the crossbar 5 at the forward end of the plowframe.'`

' For the purpose of'adjusting the plow for depth of plowing, thedevices now -tobe de'A scribed may be' employed: Levers G8; 68 areprovided between their ends with hub. portions 69 loosely meuntedon thebearings of the projecting portions of the shaft 34 andtheselevers.carryrollersj70 attheir lower ends to engage thecianks oftheaxles 14 and 19. Standards 71are secured to the forward portion of theplow frame, (preferably to the clevices 6) and braced, as at 71a.Sleeves72 vare swiveled lor `pivotally connected to the upper ends ofsaid stand.

a-rds and shaftsn 73y pass through these to regulate the depth at whichIthe sleeves.v The shafts 73aremounted'to turn freely in the sleeves 472but are prevented from `moving longitudinally therethrough, aand saidshafts are provided with threaded portions 74 and pass through threadedsleeves`75 swiveled or lpivotally connected with the upperfends of thelevers 68.'v At their forward ends, the shafts '73' are provided withcranks 7 6` to facilitate their manual'manipulation. It is apparent thatby turning the shafts 7 3, the levers 68 may be so moved that theircooperation with vthe crank axles will effect such adjustment of thelatter relatively `to the plowrframe yas plow bases may enter theground.

The arm 1821i (which is, in effect keyed to the crank axle 14); themember 18,"and the arm 18CV on the furrow wheel-crank axle 19,constitute, in addition toy thefunctions hereinbefore mentioned, stopdevices. y'The arm 18.is of suiiicient length to engage the fhub of thelever 68 at the'furrow sidei'of') tion when'theplow is inraised positionand l thus insure the maintenance ofthe axis Vof the furrow wheel inadvance of the axis of the furrow wheel-axle 19, asfotherwise the plowVcould not be caused to drop,1 v

i .By adjusting the member 18", the plow may be leveled, when it isdesired to vset the furrow wheel higheror lower relatively to the landwheel so as to 'permit the furrow `wheel `to run. on the mound .thrownup when a. previous mound has been made. 1 I do not claim herein thefeatures for effectingfdepth adjustment, the same being subject mattei'.of application for patent filed by Heylman, October 17, 1919, vSerialNo. 331,288; nor the construction including independently-movable crankaxles, they same beingv embodied in application y filed by E.
